NASA and Boeing continue to make progress toward the company’s second uncrewed flight test of the CST-100 Starliner spacecraft prior to flying astronauts to the International Space Station as part of NASA’s Commercial Crew Program.
The Commercial Crew Program currently is targeting no earlier than December 2020 for launch of the uncrewed Orbital Flight Test-2 (OFT-2) pending hardware readiness, flight software qualification, and launch vehicle and space station manifest priorities.
Over the summer, Boeing’s Starliner team focused on readying the next spacecraft for its upcoming flight tests as well as making improvements identified during various review processes throughout the beginning of the year. NASA also announced an additional crew assignment for its first operational mission, NASA’s Boeing Starliner-1, with astronauts to the space station.
When Boeing’s Orbital Flight Test (OFT) launches on Dec. 20, 2019, it will be a major step toward returning human spaceflight capability to the U.S.
The uncrewed mission for NASA’s Commercial Crew Program will rendezvous and dock Boeing’s CST-100 Starliner spacecraft with the International Space Station and return to Earth on Dec. 28. Starliner will launch atop a United Launch Alliance Atlas V rocket from Space Launch Complex 41 (SLC-41) at Cape Canaveral Air Force Station in Florida.
“This test flight will give us valuable data about Starliner’s performance in the actual environment through each phase of flight and demonstrate its capability to transport crew to the space station and bring them home safely,” said Trip Healey, NASA’s mission manager for OFT. “Being on the cusp of this huge moment in history is really exciting.”
Data from the mission will validate spacecraft system performance and will move Starliner farther down the path toward its first flight with astronauts aboard — Boeing’s Crew Flight Test (CFT).
The United Launch Alliance Atlas V rocket that will launch Boeing’s CST-100 Starliner on the Crew Flight Test (CFT) mission to the International Space Station for NASA’s Commercial Crew Program emerged on Thursday from the production factory in Decatur, Alabama for transport in a giant cargo ship to Cape Canaveral Air Force Station in Florida.
The rocket, known as AV-082, will launch Starliner and its crew of NASA astronauts Mike Fincke and Nicole Mann, and Boeing astronaut Chris Ferguson to the station following the spacecraft’s maiden voyage, the uncrewed Orbital Flight Test targeted for August.
From the manufacturing facility in Decatur, Alabama, the Atlas V booster stage and Dual Engine Centaur upper stage were moved down the road for loading into the Mariner vessel docked nearby. The 312-foot-long ship is purpose-built to navigate both shallow waters of rivers and ocean travel to reach ULA’s launch sites. It has been making the trek from Decatur to Cape Canaveral since 2001.
Once at Cape Canaveral, the Atlas V will begin integrated operations and processing for the CFT launch.
NASA selected Boeing and SpaceX to transport crew to the space station from the United States, returning the nation’s human spaceflight launch capability. These integrated spacecraft, rockets and associated systems will carry up to four astronauts on NASA missions.
Regular commercial transportation using Boeing’s Starliner and SpaceX’s Crew Dragon spacecraft to and from the station will enable expanded station use and additional research time aboard the orbiting laboratory. Research on the space station helps address the challenges of moving humanity forward to the Moon and Mars as we learn how to keep astronauts healthy during long-duration space travel and demonstrate technologies for human and robotic exploration beyond low-Earth orbit.
Boeing and Aerojet Rocketdyne have begun a series of developmental hot-fires tests with two launch abort engines similar to the ones that will be part of Boeing’s Starliner service module. The engines, designed to maximize thrust build-up, while minimizing overshoot during start up, will be fired between half a second and 3 seconds each during the test campaign. If the Starliner’s four launch abort engines were used during an abort scenario, they would fire between 3 and 5.5 seconds, with enough thrust to get the spacecraft and its crew away from the rocket, before splashing down in the ocean under parachutes.
Recently, Aerojet Rocketdyne also completed delivery of the first set of hardware for Starliner’s service module propulsion system.
The Starliner is under development in collaboration with NASA’s Commercial Crew Program for crew missions to the International Space Station.
